OSCAR L. BROWN, OF HOPKINTON, MASSACHUSETTS.

IMPROVEMENT iN HEMMERS.

Specication forming part of Letters Patent No. 143,433, dated October 7,1873; application filed August 21, 1873. l

To all whom it may concern:

Be it known that I, OSCAR L. BROWN, of Hopkinton, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Hemmers and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and useit, reference being had to the accompanying drawings, which form part ofthis specification.

The nature of my invention relates to an improvement in hemmers; and itconsists in pivoting to its side an adjustable flanged gage, so as toregulate the width of the hem and facilitate the introduction of thematerial, as will be more fully described hereafter.

Figure l is an enlarged perspective view of my invention. Fig. 2 is anenlarged end view of the same. 4

a represents an ordinary hemmer, which is secured to the fame of themachine in the usual manner. Pivoted to its side is the gage c, whichcan be freely opened and closed at will, and which has a flange, 1,formed upon its inner side, as shown in Fig. 2, which catches `upon thetop of the hemmer and prevents the gage from moving too far downward.Instead of this flange, the pivoted end of the gage may be so formed asto catch under the shoulder 2 and answer the same purpose.

While open, the cloth can be much more easily inserted than in thecommon hemmer, and the hem will be begun as perfectly as any other part.The gage, when closed, acts as a guide to the cloth as it passesthrough.

By leaving the gage slightly raised the cloth will readily pass underit, and hems of any desired width can be made by simply folding thecloth to the width wanted.

Having thus described my invention, I claim- The hemmer a, incombination with the pivoted vertically-moving gage c, provided with asuitable flange or stop, substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this16th day of August, 1873.

OSCAR L. BROWN.
